Oil-Feeders for Oil-Stoves, oi whichthe fol-= lowing is a specification.

This invention relates to automatic oilfeedcrs such as are used for feeding oil, to oil stoves or heaters in freight-cars; and it has for its object the improvements in construction which i will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a front elevation of my-iinproved feeder with connecting-pipes; Fig. 2, a section of the same on liners a of Fig. 1.

The same letters of reference indicate the same parts in all the drawings.

l in the drawings, (t represents a casting h ingwithin it the cavity OfOli-CllfiDlbBl'b. The lower end of the casting is internally screw- 7 threaded to engage with the externally-screwage with the internal so that a disk 3 riding disks with threaded flange c on the cap The said cap has a hexagonal head, to which a wrench is applied in applying or removing the p. The upper end of the casting'has a flange'or neck i l i a, which is externally and internally screwthreaded, said upper end inner cap or plug (1, which is threaded to en'- thrcads on the neck The plug d is hollow ant. has a small orifice or oil-passage in its head, through which the oil iiows into the chamber 7).

e.represents outer cap, which is internally scrcw-threaded to engage with the external threads on the neck. a. In thehead of said outer cap is a passage 9, through which the oil from the storage-reservoir flows to the space between the caps (l and c. The

end of the outer cap 6 is co intcrsunk, f may be inserted, having a central hole for the passage of oil. By proholcs oi diilcrcnt sizes I can regulate the rate of inilow of oil. The oil passes out of chamber 1) to the Store, as will be hereinafter described, through the passage m in the lower portion of the casting.

To regulate the entrance of 'oil through the upper assage (1, provide the valve said mire 1 By being closed by the chamberb. When th her, the iioatis raised and presses the valye has a socketi', in which is loosely fitted a rod which is secured to a float within the' oile oil rises in thechami by means of the rod jagainst its seat d" 1]]. he plug (1, thus closing the opening in the" plug and preventing entrance of oil into the chamber b, As the oil is used and the level of the oil in the chamber 1) lowered, the float 6c' and valve fall and the passage d is again opened. 'lo guide the float, the rod j is extended down into the recess 0 of the lower cap 0. It is desirable that thefloatmay be 'egulated so as to keep the oil at any desired 65 height in the chamber 1), To this end the rod j is located in a passage through the float 7c, and is securedtherein by solder. When it is desired to change the position oi the float on the wire, the solder is meltkadand-the wireqo drawn to any new position, where it will be held by the solder when cool. r An overflow-pipe Z is provided in one side of the casting a to permit the escape of oil 7 from the chamber bin case any derangement of the valve or float should permit the accuinnlation of too much oil in said chamber, it. being desirable to keep the quantity o'i oil j uniform. An increased accumulation in the chamber creates a "head or pressure which causes the oil to flow too rapidly to the stove and causes a dangerous increase of heat. lfhis feature is an important one, as, if the. head of oil is at any time considerably increased, the flow will be necessarily increased in any form of ieed'enand the increased supply-of oil afiorded the heater will .anse the same to generate an amount of heat which may set the wood-Work or contents of the car on fire. The overflow-opening also. admits the atmospheric pressure to the chamber 12 atall times; otherwise apartial Vacuum would be formed as the oil falls and the oil would not flow flOlll the chamber. freely.v On the side of the casting is a circular boss 0/, hav- 5 ing a stud p, on. which is journaled a rotary K diskor rial D, by means of which the outflow of oil is regulated. On the edge of the dial are a series of protuberances n, in which are passages rawhich are arranged to'coin- I00 cidc with theontlet m of the oii-ch'amber.

the rotation of the dial any one of these any size of opening for the outflowof oil may be quickly adjusted, my improved feeder secures a sure, exact, perfect regulation of the flow of oil. The cup t, into-which the oil drops from the passage n, is connected with a pipe u, which is a section of the conduit through which the oil passes to the stove or heater. The pipe u is vertically movable in t the larger pipe 2), into his countersunk or form a shoulder'u within, between t e lower end of the the spring to, which uand dial; but b passages with the'outlet m, so that the oil may flow extends outwardly through t 5 dial; and therefore allows the oil to drop from said margin into a collector t, hereinafter described. The inner side of the dial is countersunk around the passages tionof disks 0, which-are removably applied,

to the dial, each disk having an opening for the passage of oil. The size of the opening is varied in the different disks, so that by bringing with the e margin of the y pressure of the hand' on the cup manner; but I prefer to provide nine passages arranged in groups of three. The openings 0 in the disks of the same group of passages are of the same size, but they are of different sizes in the difierent groups. Thus there are three sizes of openings and three of each size, thereby providingfor proper regulation of the outflow of oil, and in case any opening becomes clogged affording two other openings of the ame size to which recourse may be had. Since the disks are removably inserted,

I 2. In an automatic oil-feeder,'the combination of an oil-chamber having inlet andputlet T valve to control the mospheric pressure to the passages n, and thus allow the oil to drop freely therefrom. 40 The stud p is screwed into the boss a and forms a bearing rotated. The head of the stud p has a flange 10', between which and the dial is laced a spring q, whose office is to press the dial closely against the 'face of the boss. The faces of both boss and dial are ground so that the connection is close and no oil is allowed to escape between them. To hold the dial in position with any one of the passages 92 in connection with the outlet m, I provide above each passage n a recess 7", into which a latch or bolt 7" is pushed by a spring whenever the recess is brought opposite the bolt by the rotation of the dial, said bolt-being located in a-cavity or socket in the boss a. The bolt and sockets are so formed that when the dial is rotated by hand the bolt will yield, the force of its spring being sufficient only to prevent the accidental rotation of the dial. I provide a ring of metal on the outside of the dial, enaranged above the'outlet-passage, whereby air bling the same to be more easily grasped by is. admitted to the chamber and an undue the hand, and also making it easier to give a smooth finish to the edge. 7
